SpringBoot集成Spring Security全解：从入门到精通实战指南（亲测可用）

一、Spring Security基础概念与核心原理

Spring Security是Spring家族中负责认证(Authentication)和授权(Authorization)的框架，它为基于Java EE的企业应用提供了全面的安全服务。我们先从最基础的概念开始，逐步深入。

1.1 认证(Authentication)与授权(Authorization)的区别

是

否

是

否

用户请求资源

是否认证?

是否有权限?

要求登录

允许访问

拒绝访问

认证和授权是安全框架的两个核心概念，它们的关系可以用以下表格说明：

对比维度	认证(Authentication)	授权(Authorization)
定义	验证用户身份的真实性	验证用户是否有权限执行特定操作
关注点	你是谁	你能做什么
典型实现	用户名密码、指纹、短信验证码等	角色检查、权限检查等
执行时机	通常在授权之前	通常在认证成功之后
示例	登录系统	访问管理员后台

1.2 Spring Security核心架构

Spring Security的核心架构主要包含以下组件：

1. SecurityContextHolder：存储安全上下文信息
2. SecurityContext：包含当前认证对象
3. Authentication：代表认证请求或已认证的主体
4. UserDetails：构建认证对象的用户信息
5. UserDetailsService：加载用户特定数据
6. AuthenticationManager：认证流程的入口点
7. ProviderManager：AuthenticationManager的实现
8. AuthenticationProvider：特定认证机制实现
9. AbstractSecurityInterceptor：授权拦截器

// 典型认证流程代码示例
public class AuthenticationExample {
    public void authenticate(String username, String password) {
        AuthenticationManager authenticationManager = // 获取认证管理器
        Authentication authentication = new UsernamePasswordAuthenticationToken(username, password);
        
        try {
            Authentication result = authenticationManager.authenticate(authentication);
            SecurityContextHolder.getContext().setAuthentication(result);
            System.out.println("认证成功: " + result.getName());
        } catch (AuthenticationException e) {
            System.out.println("认证失败: " + e.getMessage());
        }
    }
}

1.3 Spring Security过滤器链

Spring Security基于Servlet过滤器实现，其核心过滤器链如下：

客户端请求

SecurityContextPersistenceFilter

UsernamePasswordAuthenticationFilter

BasicAuthenticationFilter

RememberMeAuthenticationFilter

AnonymousAuthenticationFilter

ExceptionTranslationFilter

FilterSecurityInterceptor

应用资源

每个过滤器的功能说明：

1. SecurityContextPersistenceFilter：在请求之间持久化SecurityContext
2. UsernamePasswordAuthenticationFilter：处理表单登录认证
3. BasicAuthenticationFilter：处理HTTP基本认证
4. RememberMeAuthenticationFilter：处理"记住我"功能
5. AnonymousAuthenticationFilter：为匿名用户创建Authentication对象
6. ExceptionTranslationFilter：处理安全异常
7. FilterSecurityInterceptor：进行授权决策

二、SpringBoot集成Spring Security基础配置

2.1 创建项目并添加依赖

首先创建一个SpringBoot项目，在pom.xml中添加Spring Security依赖：

<dependencies>
    <dependency>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-securityartifactId>
    dependency>
    <dependency>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-webartifactId>
    dependency>
    
dependencies>

2.2 基础安全配置类

创建一个基础的安全配置类，继承WebSecurityConfigurerAdapter：

@Configuration
@EnableWebSecurity
public class BasicSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/", "/home").permitAll()  // 允许所有人访问首页
                .anyRequest().authenticated()           // 其他请求需要认证
                .and()
            .formLogin()
                .loginPage("/login")                   // 自定义登录页
                .permitAll()                            // 允许所有人访问登录页
                .and()
            .logout()
                .permitAll();                          // 允许所有人注销
    }

    @Bean
    @Override
    public UserDetailsService userDetailsService() {
        // 内存中创建两个测试用户
        UserDetails user = User.withDefaultPasswordEncoder()
            .username("user")
            .password("password")
            .roles("USER")
            .build();

        UserDetails admin = User.withDefaultPasswordEncoder()
            .username("admin")
            .password("admin")
            .roles("ADMIN")
            .build();

        return new InMemoryUserDetailsManager(user, admin);
    }
}

2.3 控制器代码示例

创建几个简单的控制器来测试我们的安全配置：

@Controller
public class HomeController {

    @GetMapping("/")
    public String home() {
        return "home";  // 首页模板
    }

    @GetMapping("/hello")
    @ResponseBody
    public String hello() {
        return "Hello, Spring Security!";
    }

    @GetMapping("/admin")
    @ResponseBody
    public String admin() {
        return "Admin Dashboard";
    }
}

2.4 自定义登录页面

在resources/templates下创建login.html：

DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>Login Pagetitle>
head>
<body>
    <div th:if="${param.error}">
        无效的用户名或密码
    div>
    <div th:if="${param.logout}">
        您已成功注销
    div>
    
    <form th:action="@{/login}" method="post">
        <div>
            <label>用户名: <input type="text" name="username"/>label>
        div>
        <div>
            <label>密码: <input type="password" name="password"/>label>
        div>
        <div>
            <input type="submit" value="登录"/>
        div>
    form>
body>
html>

三、认证机制深度解析

3.1 基于数据库的用户认证

实际项目中，我们通常不会使用内存用户，而是从数据库加载用户信息。下面展示如何实现基于数据库的认证。

3.1.1 用户实体类

@Entity
@Table(name = "users")
public class User implements UserDetails {
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(unique = true, nullable = false)
    private String username;
    
    @Column(nullable = false)
    private String password;
    
    @Column(nullable = false)
    private boolean enabled;
    
    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(
        name = "user_roles",
        joinColumns = @JoinColumn(name = "user_id"),
        inverseJoinColumns = @JoinColumn(name = "role_id"))
    private Set<Role> roles = new HashSet<>();

    // 实现UserDetails接口的方法
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return roles.stream()
            .map(role -> new SimpleGrantedAuthority(role.getName()))
            .collect(Collectors.toList());
    }
    
    @Override
    public boolean isAccountNonExpired() { return true; }
    
    @Override
    public boolean isAccountNonLocked() { return true; }
    
    @Override
    public boolean isCredentialsNonExpired() { return true; }
    
    // 其他getter和setter...
}

3.1.2 角色实体类

@Entity
@Table(name = "roles")
public class Role {
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(unique = true, nullable = false)
    private String name;
    
    // 其他getter和setter...
}

3.1.3 自定义UserDetailsService

@Service
public class CustomUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userRepository.findByUsername(username)
            .orElseThrow(() -> new UsernameNotFoundException("用户不存在: " + username));
            
        return new org.springframework.security.core.userdetails.User(
            user.getUsername(),
            user.getPassword(),
            user.isEnabled(),
            true,  // accountNonExpired
            true,  // credentialsNonExpired
            true,  // accountNonLocked
            user.getAuthorities());
    }
}

3.1.4 更新安全配置

@Configuration
@EnableWebSecurity
public class DatabaseSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private CustomUserDetailsService userDetailsService;
    
    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService)
            .passwordEncoder(passwordEncoder);
    }
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
    
    // 其他配置...
}

3.2 密码加密策略

Spring Security支持多种密码加密方式，以下是常见加密方式的对比：

加密方式	安全性	速度	特点
BCrypt	高	中等	自动加盐，内置工作因子，推荐使用
Argon2	非常高	慢	密码哈希竞赛获胜者，抗GPU/ASIC攻击，但配置复杂
PBKDF2	中	慢	可配置迭代次数，简单易用
SCrypt	高	慢	内存密集型，抗硬件攻击
Plain Text(不加密)	无	快	绝对不要在生产环境使用
SHA-256/SHA-512	低	快	单向哈希但无加盐，易受彩虹表攻击

BCrypt是最常用的加密方式，使用方法如下：

@Bean
public PasswordEncoder passwordEncoder() {
    // 推荐使用BCryptPasswordEncoder，强度10-12
    return new BCryptPasswordEncoder(12);
}

四、授权机制深度解析

4.1 基于角色的访问控制(RBAC)

Spring Security支持基于角色的访问控制，可以通过注解或配置方式实现。

4.1.1 方法级安全控制

在配置类上添加@EnableGlobalMethodSecurity注解：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(
    prePostEnabled = true,   // 启用@PreAuthorize和@PostAuthorize
    securedEnabled = true,   // 启用@Secured
    jsr250Enabled = true)    // 启用JSR-250注解如@RolesAllowed
public class MethodSecurityConfig extends WebSecurityConfigurerAdapter {
    // 配置...
}

然后在控制器方法上使用注解：

@RestController
@RequestMapping("/api")
public class ApiController {

    @GetMapping("/user")
    @PreAuthorize("hasRole('USER')")
    public String userEndpoint() {
        return "普通用户可访问";
    }

    @GetMapping("/admin")
    @PreAuthorize("hasRole('ADMIN')")
    public String adminEndpoint() {
        return "管理员可访问";
    }

    @GetMapping("/both")
    @PreAuthorize("hasAnyRole('USER', 'ADMIN')")
    public String bothEndpoint() {
        return "用户和管理员都可访问";
    }
}

4.1.2 基于表达式的访问控制

Spring Security支持强大的SpEL表达式，可以实现更复杂的访问控制逻辑：

@RestController
@RequestMapping("/account")
public class AccountController {

    @GetMapping("/{id}")
    @PreAuthorize("hasPermission(#id, 'account', 'read')")
    public Account getAccount(@PathVariable Long id) {
        // 实现...
    }

    @PostMapping
    @PreAuthorize("hasRole('ADMIN') or #account.owner == authentication.name")
    public Account createAccount(@RequestBody Account account) {
        // 实现...
    }
}

4.2 基于权限的访问控制(ABAC)

除了基于角色的访问控制，Spring Security还支持基于权限的细粒度控制。

4.2.1 自定义权限评估器

@Component
public class CustomPermissionEvaluator implements PermissionEvaluator {

    @Autowired
    private AccountRepository accountRepository;

    @Override
    public boolean hasPermission(Authentication authentication, 
                                Object targetDomainObject, 
                                Object permission) {
        if (authentication == null || !(permission instanceof String)) {
            return false;
        }
        
        String username = authentication.getName();
        Account account = (Account) targetDomainObject;
        
        return account.getOwner().equals(username) || 
               authentication.getAuthorities().stream()
                   .anyMatch(a -> a.getAuthority().equals("ROLE_ADMIN"));
    }

    @Override
    public boolean hasPermission(Authentication authentication, 
                                Serializable targetId, 
                                String targetType, 
                                Object permission) {
        if (authentication == null || !(targetType instanceof String) || !(permission instanceof String)) {
            return false;
        }
        
        Account account = accountRepository.findById((Long) targetId)
            .orElseThrow(() -> new ResourceNotFoundException("Account not found"));
            
        return hasPermission(authentication, account, permission);
    }
}

4.2.2 注册权限评估器

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {

    @Autowired
    private CustomPermissionEvaluator permissionEvaluator;

    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        DefaultMethodSecurityExpressionHandler expressionHandler = 
            new DefaultMethodSecurityExpressionHandler();
        expressionHandler.setPermissionEvaluator(permissionEvaluator);
        return expressionHandler;
    }
}

五、高级特性与定制化

5.1 自定义认证流程

5.1.1 自定义认证过滤器

public class JwtAuthenticationFilter extends OncePerRequestFilter {

    @Autowired
    private JwtTokenProvider tokenProvider;

    @Autowired
    private CustomUserDetailsService userDetailsService;

    @Override
    protected void doFilterInternal(HttpServletRequest request,
                                    HttpServletResponse response,
                                    FilterChain filterChain) throws ServletException, IOException {
        try {
            String jwt = getJwtFromRequest(request);
            
            if (StringUtils.hasText(jwt) && tokenProvider.validateToken(jwt)) {
                Long userId = tokenProvider.getUserIdFromJWT(jwt);
                
                UserDetails userDetails = userDetailsService.loadUserById(userId);
                UsernamePasswordAuthenticationToken authentication = 
                    new UsernamePasswordAuthenticationToken(
                        userDetails, null, userDetails.getAuthorities());
                authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
                
                SecurityContextHolder.getContext().setAuthentication(authentication);
            }
        } catch (Exception ex) {
            logger.error("无法设置用户认证", ex);
        }

        filterChain.doFilter(request, response);
    }

    private String getJwtFromRequest(HttpServletRequest request) {
        String bearerToken = request.getHeader("Authorization");
        if (StringUtils.hasText(bearerToken) && bearerToken.startsWith("Bearer ")) {
            return bearerToken.substring(7);
        }
        return null;
    }
}

5.1.2 自定义认证提供器

public class CustomAuthenticationProvider implements AuthenticationProvider {

    @Autowired
    private UserDetailsService userDetailsService;
    
    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        String username = authentication.getName();
        String password = authentication.getCredentials().toString();
        
        UserDetails user = userDetailsService.loadUserByUsername(username);
        
        if (!passwordEncoder.matches(password, user.getPassword())) {
            throw new BadCredentialsException("密码错误");
        }
        
        if (!user.isEnabled()) {
            throw new DisabledException("用户已被禁用");
        }
        
        return new UsernamePasswordAuthenticationToken(
            user, password, user.getAuthorities());
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }
}

5.2 OAuth2集成

Spring Security提供了对OAuth2的全面支持，下面展示如何集成OAuth2登录。

5.2.1 添加依赖

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-oauth2-clientartifactId>
dependency>

5.2.2 配置OAuth2客户端

@Configuration
public class OAuth2LoginConfig {

    @Bean
    public ClientRegistrationRepository clientRegistrationRepository() {
        return new InMemoryClientRegistrationRepository(this.googleClientRegistration());
    }

    private ClientRegistration googleClientRegistration() {
        return ClientRegistration.withRegistrationId("google")
            .clientId("your-client-id")
            .clientSecret("your-client-secret")
            .clientAuthenticationMethod(ClientAuthenticationMethod.BASIC)
            .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
            .redirectUri("{baseUrl}/login/oauth2/code/{registrationId}")
            .scope("openid", "profile", "email")
            .authorizationUri("https://accounts.google.com/o/oauth2/v2/auth")
            .tokenUri("https://www.googleapis.com/oauth2/v4/token")
            .userInfoUri("https://www.googleapis.com/oauth2/v3/userinfo")
            .userNameAttributeName(IdTokenClaimNames.SUB)
            .clientName("Google")
            .build();
    }
}

5.2.3 配置安全

@Configuration
@EnableWebSecurity
public class OAuth2SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/", "/login**").permitAll()
                .anyRequest().authenticated()
                .and()
            .oauth2Login()
                .loginPage("/login")
                .userInfoEndpoint()
                    .userService(customOAuth2UserService())
                    .and()
                .successHandler(oAuth2AuthenticationSuccessHandler())
                .and()
            .logout()
                .logoutSuccessUrl("/")
                .permitAll();
    }
    
    @Bean
    public OAuth2UserService<OAuth2UserRequest, OAuth2User> customOAuth2UserService() {
        return new CustomOAuth2UserService();
    }
    
    @Bean
    public AuthenticationSuccessHandler oAuth2AuthenticationSuccessHandler() {
        return new CustomOAuth2AuthenticationSuccessHandler();
    }
}

六、安全防护与最佳实践

6.1 常见安全威胁与防护

6.1.1 CSRF防护

Spring Security默认启用CSRF防护，对于REST API可以禁用：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .csrf()
            .ignoringAntMatchers("/api/**")  // 对API禁用CSRF
            .and()
        // 其他配置...
}

6.1.2 CORS配置

@Bean
public CorsConfigurationSource corsConfigurationSource() {
    CorsConfiguration configuration = new CorsConfiguration();
    configuration.setAllowedOrigins(Arrays.asList("https://trusted.com"));
    configuration.setAllowedMethods(Arrays.asList("GET", "POST", "PUT", "DELETE"));
    configuration.setAllowedHeaders(Arrays.asList("authorization", "content-type"));
    configuration.setAllowCredentials(true);
    
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", configuration);
    return source;
}

6.2 安全头配置

Spring Security默认添加了一些安全相关的HTTP头，可以自定义：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .headers()
            .contentSecurityPolicy("default-src 'self'")
            .and()
            .frameOptions()
                .sameOrigin()
            .and()
            .xssProtection()
                .block(true)
            .and()
            .httpStrictTransportSecurity()
                .includeSubDomains(true)
                .maxAgeInSeconds(31536000);
}

七、实战案例：构建完整的认证授权系统

7.1 JWT认证实现

7.1.1 JWT工具类

@Component
public class JwtTokenProvider {

    @Value("${app.jwt.secret}")
    private String jwtSecret;

    @Value("${app.jwt.expirationInMs}")
    private int jwtExpirationInMs;

    public String generateToken(Authentication authentication) {
        UserPrincipal userPrincipal = (UserPrincipal) authentication.getPrincipal();
        
        Date now = new Date();
        Date expiryDate = new Date(now.getTime() + jwtExpirationInMs);
        
        return Jwts.builder()
                .setSubject(Long.toString(userPrincipal.getId()))
                .setIssuedAt(new Date())
                .setExpiration(expiryDate)
                .signWith(SignatureAlgorithm.HS512, jwtSecret)
                .compact();
    }

    public Long getUserIdFromJWT(String token) {
        Claims claims = Jwts.parser()
                .setSigningKey(jwtSecret)
                .parseClaimsJws(token)
                .getBody();
                
        return Long.parseLong(claims.getSubject());
    }

    public boolean validateToken(String authToken) {
        try {
            Jwts.parser().setSigningKey(jwtSecret).parseClaimsJws(authToken);
            return true;
        } catch (SignatureException ex) {
            logger.error("Invalid JWT signature");
        } catch (MalformedJwtException ex) {
            logger.error("Invalid JWT token");
        } catch (ExpiredJwtException ex) {
            logger.error("Expired JWT token");
        } catch (UnsupportedJwtException ex) {
            logger.error("Unsupported JWT token");
        } catch (IllegalArgumentException ex) {
            logger.error("JWT claims string is empty.");
        }
        return false;
    }
}

7.1.2 JWT认证控制器

@RestController
@RequestMapping("/api/auth")
public class AuthController {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private JwtTokenProvider tokenProvider;

    @PostMapping("/signin")
    public ResponseEntity<?> authenticateUser(@Valid @RequestBody LoginRequest loginRequest) {
        Authentication authentication = authenticationManager.authenticate(
                new UsernamePasswordAuthenticationToken(
                        loginRequest.getUsername(),
                        loginRequest.getPassword()
                )
        );

        SecurityContextHolder.getContext().setAuthentication(authentication);
        
        String jwt = tokenProvider.generateToken(authentication);
        return ResponseEntity.ok(new JwtAuthenticationResponse(jwt));
    }
}

7.2 多因素认证(MFA)实现

7.2.1 短信验证码服务

@Service
public class SmsService {

    @Value("${twilio.accountSid}")
    private String accountSid;
    
    @Value("${twilio.authToken}")
    private String authToken;
    
    @Value("${twilio.phoneNumber}")
    private String fromPhoneNumber;

    public void sendVerificationCode(String phoneNumber, String code) {
        Twilio.init(accountSid, authToken);
        
        Message message = Message.creator(
                new PhoneNumber(phoneNumber),
                new PhoneNumber(fromPhoneNumber),
                "您的验证码是: " + code)
            .create();
    }
}

7.2.2 MFA认证流程

User System SMS 输入用户名密码 验证用户名密码 要求输入短信验证码 发送验证码 输入验证码 验证验证码 登录成功 验证码错误 alt [验证成功] [验证失败] 用户名或密码错误 alt [验证成功] [验证失败] User System SMS

八、性能优化与监控

8.1 安全过滤器性能优化

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers(
        "/css/**", 
        "/js/**", 
        "/images/**", 
        "/webjars/**",
        "/favicon.ico",
        "/actuator/**");
}

8.2 安全事件监控

@Component
public class CustomAuthenticationEventListener {
    
    private static final Logger logger = LoggerFactory.getLogger(CustomAuthenticationEventListener.class);
    
    @EventListener
    public void handleAuthenticationSuccess(AuthenticationSuccessEvent event) {
        logger.info("用户 {} 登录成功", event.getAuthentication().getName());
        // 记录登录日志...
    }
    
    @EventListener
    public void handleAuthenticationFailure(AbstractAuthenticationFailureEvent event) {
        logger.warn("用户 {} 登录失败: {}", 
            event.getAuthentication().getName(), 
            event.getException().getMessage());
        // 记录失败尝试...
    }
    
    @EventListener
    public void handleLogoutSuccess(LogoutSuccessEvent event) {
        logger.info("用户 {} 注销成功", event.getAuthentication().getName());
        // 记录注销日志...
    }
}

九、测试策略

9.1 单元测试示例

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class SecurityTest {

    @Autowired
    private MockMvc mockMvc;
    
    @Test
    @WithMockUser(username = "user", roles = {"USER"})
    public void whenUserAccessUserEndpoint_thenOk() throws Exception {
        mockMvc.perform(get("/api/user"))
            .andExpect(status().isOk());
    }
    
    @Test
    @WithMockUser(username = "user", roles = {"USER"})
    public void whenUserAccessAdminEndpoint_thenForbidden() throws Exception {
        mockMvc.perform(get("/api/admin"))
            .andExpect(status().isForbidden());
    }
    
    @Test
    public void whenUnauthenticated_thenRedirectToLogin() throws Exception {
        mockMvc.perform(get("/api/user"))
            .andExpect(status().is3xxRedirection());
    }
}

9.2 集成测试示例

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class OAuth2LoginTest {

    @LocalServerPort
    private int port;
    
    @Test
    public void whenLoginWithValidCredentials_thenSuccess() {
        RestTemplate restTemplate = new RestTemplate();
        
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
        
        MultiValueMap<String, String> map = new LinkedMultiValueMap<>();
        map.add("username", "user");
        map.add("password", "password");
        
        HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<>(map, headers);
        
        ResponseEntity<String> response = restTemplate.postForEntity(
            "http://localhost:" + port + "/login", request, String.class);
            
        assertThat(response.getStatusCodeValue()).isEqualTo(200);
        assertThat(response.getHeaders().get("Set-Cookie")).isNotNull();
    }
}

十、常见问题与解决方案

10.1 常见问题排查表

问题现象	可能原因	解决方案
登录后重定向到/login?error	用户名/密码错误	检查用户名密码，确保UserDetailsService返回正确用户
403 Forbidden	CSRF令牌缺失或无效	确保表单包含CSRF令牌，或对API禁用CSRF
无法注入AuthenticationManager	未正确暴露Bean	在配置类中添加@Bean注解覆盖authenticationManagerBean()方法
密码编码器不匹配	使用了错误的密码编码器	确保注册的PasswordEncoder与存储密码时使用的编码器一致
权限注解不生效	未启用方法级安全	检查是否添加了@EnableGlobalMethodSecurity注解
静态资源被拦截	安全配置未忽略静态资源	在configure(WebSecurity web)方法中配置忽略静态资源路径

10.2 调试技巧

1. 启用调试日志：在application.properties中添加

   logging.level.org.springframework.security=DEBUG
   

2. 检查过滤器链：添加自定义过滤器时注意顺序

   http.addFilterBefore(new CustomFilter(), UsernamePasswordAuthenticationFilter.class);
   

3. 检查SecurityContext：在关键点打印SecurityContext内容

   SecurityContext context = SecurityContextHolder.getContext();
   System.out.println("Authentication: " + context.getAuthentication());
   

4. 使用Spring Security测试支持：

   @WithMockUser(username="admin", roles={"ADMIN"})
   @Test
   public void testAdminEndpoint() {
       // 测试代码
   }
   

十一、Spring Security 5.x新特性

11.1 OAuth2资源服务器

@Configuration
@EnableWebSecurity
public class OAuth2ResourceServerConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .anyRequest().authenticated()
                .and()
            .oauth2ResourceServer()
                .jwt()
                .decoder(jwtDecoder());
    }
    
    @Bean
    public JwtDecoder jwtDecoder() {
        return NimbusJwtDecoder.withJwkSetUri("https://idp.example.com/.well-known/jwks.json").build();
    }
}

11.2 响应式安全支持

@EnableWebFluxSecurity
public class ReactiveSecurityConfig {

    @Bean
    public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
        return http
            .authorizeExchange()
                .pathMatchers("/public/**").permitAll()
                .anyExchange().authenticated()
                .and()
            .httpBasic().and()
            .formLogin().and()
            .build();
    }
}
